MR arthrography of the adult acetabular capsular-labral complex: correlation with surgery and anatomy.C Czerny, S Hofmann, M Urban, C Tschauner, A Neuhold, Pretterklieber, P Recht J KramerAudio Available | Share
PURPOSE: To evaluate whether dental computed tomography (CT) can depict the frequency, diameter, position, and direction of vessels entering mandible through lingual bone canals. MATERIALS AND METHODS: Thirty-two consecutive patients underwent preimplantation CT lower jaw examination for presence, number, location, canals mandible. In addition, three cadaver mandibles were investigated with subsequently dissected to confirm findings. RESULTS: All demonstrated at least one vascular canal, 20...
We studied the function of first tarsometatarsal joint in 100 specimens 53 cadavers. The study showed that an adduction and abduction movement described earlier was present only approximately 10% specimens. Moreover, eversion average 6.2 degrees often occurs as a result dorsal displacement surfaces metatarsal relation to cuneiform by 2.6 mm. All other movements frontal, horizontal, sagittal plane can be disregarded or are this movement. New conclusions may drawn from these results,...
Background: Understanding the precise position and course of superior inferior labial arteries within upper lip lower is crucial for safe complication-free applications volumizing materials. Methods: One hundred ninety-three anatomical head specimens (56.5 percent female cadavers) Caucasian ethnicity were investigated in this large multicenter study. In total, six 3-cm-long vertical incisions performed on each (midline 1 cm medial to angles mouth) identify relation orbicularis oris muscle....
PURPOSE: To evaluate the gross and microscopic anatomy magnetic resonance (MR) imaging MR arthrographic appearance of anterior bundle ulnar collateral ligament (UCL) elbow. MATERIALS AND METHODS: The origin insertion UCL, bundle's relationship to overlying flexor tendons, presence a layered configuration were assessed through inspection dissection an elbow specimen. T1-weighted spin-echo arthrography in standard planes coronal oblique plane performed eight other specimens. Additional was...
We sought to evaluate the anatomy of posterolateral aspect knee with anatomic dissection, MR imaging, arthrography, and sectional anatomy.We assessed corner during dissection one gross specimen. imaging arthrography were performed in seven additional specimens. T1-weighted spin-echo images obtained standard planes as well coronal oblique plane. The specimens underwent after administration intraarticular contrast material sectioned into corresponding those images.At following structures...
Summary Trabecular bone is a porous mineralized tissue playing major load bearing role in the human body. Prediction of age‐related and disease‐related fractures behavior implant systems needs thorough understanding its structure–mechanical property relationships, which can be obtained using microcomputed tomography‐based finite element modeling. In this study, nonlinear model for trabecular as cohesive‐frictional material was implemented large‐scale computational framework validated by...
Despite the dominant role of bone mass in osteoporotic fractures, aging tissue properties must be thoroughly understood to improve osteoporosis management. In this context, collagen content and integrity are considered important factors, although limited research has been conducted on tensile behavior demineralized compact relation its porosity elastic native mineralized state. Therefore, study aims (i) at examining age-dependency micromechanical properties; (ii) test whether, if so which...

✓The authors compared the accuracy of laser surface scanning patient registration using commercially available Fazer (Medtronic, Inc.) with conventional procedure based on fiducial markers (FMs) in computer-assisted surgery. Four anatomical head specimens were prepared 10 titanium microscrews placed at defined locations and scanned a 16-slice spiral computed tomography unit. To compare two methods, each method was applied five times for cadaveric specimen; thus data obtained from 40...
Anatomical embalming forms a mainstay in the provision of teaching materials based on human post-mortem tissues. As consequence regulations worldwide to minimize use formaldehyde due its harmful nature, effective measures must be taken application anatomy laboratory. This study aimed identify commonalities among protocols used Austrian, German and Swiss anatomies reduce usage provide foundation for joint accreditation. Survey data all procedures, technologies chemicals related were collected...
Abstract Regional anatomy teaching forms a cornerstone of undergraduate medical education. Owing to an increase in and learning content throughout the curriculum recent years, contact hours overall course durations are under review worldwide. This study aimed assess whether shortening duration impacts gain ability identify anatomical structures correctly. Undergraduate students Johannes Kepler University Linz (JKU; n = 310) at Medical Graz (MUG; 156) participating regional courses were...
The topographical relations of the human maxillary artery (IM) in infratemporal fossa were studied 102 individuals both sexes. In majority cases (55.4%), was found a lateral position to lower head pterygoid muscle (LPTER). most these specimens IM ran also inferior alveolar, lingual and buccal nerves (type LA, 37.2%) whereas 16.1% only nerve crossed laterally LB). 4.6% occupied medial LPTER. With respect branches mandibular nerve, an IM, passing deep LPTER, lying either its main sensory MA,...
The enlarged ischiopubic synchondrosis is a well-known anatomic structure; however, little known about its physiology. In early childhood, enlargement of this occurs bilaterally, whereas before complete ossification, it frequently found unilaterally. most children, the unilateral observed in left hemipelvis, finding that was hitherto unexplained. During common athletic activities, increased ground reaction forces are exerted on weight-bearing nondominant limb, which up to 87% general...
Osteoporosis-related vertebral body fractures involve large compressive strains of trabecular bone. The small strain mechanical properties the bone such as elastic modulus or ultimate strength can be estimated using volume fraction and a second order fabric tensor, but it remains unclear if similar estimations may extended to properties. Accordingly, aim this work is identify role especially in behavior human from various anatomical locations. Trabecular biopsies were extracted T12 vertebrae...
The "prepatellar quadriceps continuation" is the appropriate designation for deepest soft-tissue layer that lies anterior to patella, related deep rectus femoris tendinous fibers. purpose of this study was define and investigate prepatellar continuation its relationship with patella in cadavers using MRI gross anatomic histologic analyses.MRI 12 fresh-frozen knee specimens performed T1-weighted sequences axial sagittal planes. Specimens were then sectioned 3-mm-thick slices correspond...
Even though the vascular supply of human patella has been object numerous studies until now, none them described in detail rich arterial provided via infrapatellar fat pad (of Hoffa). Therefore, we aimed to complete knowledge about this interesting and clinically relevant topic. Five patellae taken from voluntary body donators were studied at Department Applied Anatomy Medical University Vienna. One was dissected under operation microscope, a second made translucent by Sihlers-solution,...
